1 Claim. 1

This invention relates to a trophy engraving machine.

It is an object of the present invention to provide with a trophyengraving machine a simple and practical means for retaining the trophyin a fixed and rigid manner which is adjustable easily and readily toreceive the trophy and to release the same from the machine.

It is another object of the present invention to provide in a trophyengraving machine a convenient means for effecting the engraving outupon the trophy which has a tracer arm which can be conveniently locatedadjacent to the user and upon the patterns conveniently placed adjacentthe base of the trophy and wherein the tracer arm can be adjustedupwardly and lifted to an out-of-use position and the engravingequipment readily swung away from the opening into which the trophy hasbeen extended and retained by the holder and wherein the entirearrangement is a self-contained unit adapted to rest upon a table orflat surface in a position to be conveniently used.

Other objects of the present invention are to provide a trophy engravingmachine which is of simple construction, compact, inexpensive tomanufacture and efficient in operation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing, in which:

Fig. 1 is a top plan view of the trophy engraving machine embodying thefeatures of the present invention.

Fig. 2 is a longitudinal cross-sectional view in elevation, taken online 2-2 of Fig. 1.

Fig. 3 is a front elevational view of the engraving machine.

Fig. 4 is an enlarged cross-sectional view taken through the operatinglinkage and generally on line 44 of Fig. 1.

Referring now to the figures, l3 represents a base of heavy constructionwhich is open at the center as indicated at [I to receive a trophy l2.In the bottom of the base, there is an opening or recess |3 in which isadjustable a plate l4 having a cushion |5 therein serving to hold thetrophy in place and provide a soft rest therefor. This plate has adepending threaded shank 5 which is adjustable through a portion ll ofthe base and which is locked by a nut l8.

At opposite sides of the base, there are extended into the space H toretain the trophy a similar holding element l9. This element l9comprises a base 2| with a cushion 22 thereon adapted for engagementwith the side of the trophy. Extending from the plate 2| is a slideportion 22 which is adjustable in a recess 23 when an adjusting screw 24threadedly connected as indicated at 25 with the portion 22 is turned.

Extending from the rear of the base I0 is a bracket portion 21 on whichis journalled or piv oted a driving motor 28. This driving motor has apulley pinion 23 to which is connected a belt 3|. A projection 32 isprovided on the opposite side of the pivot connection of the drivingmotor 23 with the bracket portion 21, and to the projection there isconnected a tension spring 33, anchored to a lug 34, whereby to normallypivot the driving motor in a clockwise direction as viewed in Fig. 1whereby to tighten the belt 3|. Extending upwardly from the top of thebase II] are upright portions or bearing brackets 35 for receiving ashaft 36 to which is fixed a plate 31 on which a copying frame iscarried and which is formed with a link 39 which is pivotally mounted onthe plate by a pin 40. The opposite end of the link 39 is pivotallyconnected to an arm 4| by a pin 5 and the end of the arm 4| is pivotallyconnected to a link 38 by a pin 6. The link 4| has a bifurcated portion42 in which is pivotally connected a tracer arm 43 having a tracer point44 and a handle 45 thereon. The tracer arm 43 can be pivoted upwardlyand rearwardly when out of use or it can be extended downwardly forengagementof the tracer pin 44 with patterns or indicia 45 convenientlycarried on a bridge support 41 extending between the sides of the baseIn and upwardly therefrom.

Extending forwardly from a pivot point 48 at the end of the link 38 isan adjustable arm 49 which carries a pulley wheel 5| on which the beltBI is positioned and the pulley is carried on a shaft 52 which isjournaled in the arm 49 and carries a tool 53 at its lower end. In orderthat the tool can be adjusted by means independently of the tracer arm43, there is provided an extension 54 with a knob 55 thereon. This arm49 serves as a follower for the movements of the tracer arm 43 and isadjustably connected to the link 39 by a pivot bolt 51 which is threadedin the arm 39 as indicated at 58. The arm 49 is provided with a slot 5i!through which the bolt '51 extends. The arm 43 is formed of relativelyadjustable par ts so that the same can be extended to properly locatethe tool 53 upon the work surface. Indicia 59 is provided on the armpart to assist in the adjustment of the relatively adjustable partsthereof. Similar indicia is provided for the adjustment of the cushions22 engaging with the 3 sides of the trophy as indicated at 6| whereby toproperly center the trophy within the space H of the base.

The patterns 46 are locked in place in a channel 52 on the top of thebridge 4! by adjustable lock plates 63 having locking screws 64 thereon.

As a further support for the trophy upon the cushion 15, there isprovided at the inner end of the opening 1 I and upon the base a cleator arm 65 which is retained in place on the base by a clamping device 66and adapted so as to be adjusted to properly enter the top edge of thetrophy and wherein a soft engaging pad 61 will engage the inner surfaceof the trophy at the top thereof.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

I claim:

In a work holder for an engraving pantograph, the combination whichcomprises a base having a work receiving opening in the upper surfacewith a side wall at one side of the opening for supporting scribing andengraving tools and end walls at the ends of the opening for supportingwork positioning means, said base having a recess centrally positionedin the opening and extended. downwardly from the said opening, avertically movable horizontally disposed plate positioned in the saidrecess, an adjusting screw upon which said plate is carried extendeddownwardly from the plate through the said recess, adjusting nuts on thesaid screw for adjusting the elevation of the said plate in relation tothe upper surface of the base, vertically disposed plates positioned inthe sides of the opening of the base, means ad justably mounting thesaid vertically positioned plates in the said end Walls of the base,cushions on the said vertically and horizontally disposed plates, an armin the opening of the base positioned to extend into an opening in workpositioned on the cushion of the said vertically movable horizontallydisposed plate, a vertically disposed screw extended through said armand threaded into the base, and an adjusting nut positioned on saidvertically disposed screw for clamping the arm against the inner surfaceof work positioned on the cushion of the said horizontally disposedplate.
